Application filed July 23, 1913. Serial No. 786,834.

a rail joint chair of improved and simplified construction and which will securely grip the meeting ends of rails and hold the same in position without the necessity of extending bolts or other securing means through the rails.

Another object is to provide a hinged rai joint chair which will be of extremely simple construction, strong and durable, and highly efficient and effective in use, as well as cheap to manufacture. I With the above and other objects in view, my invention consists in certain novel constructions; combinations, and arrangements of parts to be hereinafter more fully described, claimed, and illustrated in the acc'ompanying drawings, in which,

Figure 1 is a longitudinal sectional view of my device in use; Fig.2 is-a transverse sectional view of the same: and Fig. 3 is 'a side elevational view with parts broken away.

Referring more specifically to the drawings in which similar referencecharacters designate corresponding parts throughout the several views, 1 designates the sections of the hinged rail joint chair. Each rail joint chair section comprises an upstanding rail web engaging portion 2 and a base portion 3 connected with the rail web engaging portion by the curved portion 4% adapted for engagement upon the upper faces of the bases ofthe rail sections 5. Depending from the outer marginal portions of the base 3 at a point substantially central thereof are the plates 6 provided with the oppositely directed arms 7 and 8 which extend inwardly beneath the base portions 3 of the members 1 and interlock, as clearly shown in Fig. 2, and have the hinge pin 9 extended transversely through beneath the base port1ons,'such arms 7 and 8 being of a length substantially equal to the width of the bases of'the rail sections 5. It will be understood that portions of the pase'portions 3 are cut away between the arms 7 and. 8 of each hinge member 6 to accommodate the arms 7 and 8 of the other hinge member 6 thereby all owing the inner upper corners of the arms 7 and S to project slightly above the .upper faces of the base portions 3 when the device is in open position to receive the meeting ends of the rails 5. whereby when the meeting ends of the rails are placed in the chair and pressed downwardly, the inner upper corners of the arms 7 and S will be pressed downwardly, thereby causing saidarms to swing upon the hinge pin 9 until the base portions 3 ofthe members 1 are in alinernentand the upstanding web rail engaging portions 2 are engaged against the web portion of the rail sections.

The hinged rail joint chair is placed in position with the hinge members 6 between two ties 10 and the ends of the sections'l resting upon said ties. After the rail has been secured in position in the rail joint chair, said chair is secured upon the ties 10 by spikes 11 or other suitable means engaged in the notches 12 in the longitudinal flanges 13 of the sections 1 along the lower outer edges thereof, said spikes being properly driven into the ties 10.

It will be readily seen that owing to the construction of this hinged rail joint chair, the same may be readily secured upon the ties and will securely grip the meeting ends of the rail sections and prevent movement of the same.

lVhile I have shown the preferred form of my invention, it will be understood that minor changes in the details-of construction may be made within the scope of the appended claim without departing from the spirit of my invention or sacrificing any of the advantages thereof.

What I claim is In combination with the meeting ends of rails, 22 joint chair comprising sections, each of which includes a base, a plate depending from the outer marginal portion therepin extending through the interlocking porof at a point intermediate its length, arms tions of the arms. 10 formed with such plate and base and dis- 1?. testimony whereof I hereunto afiix my posed inwardly thereof, the arms of one signature in thepreseiice of two witnesses. section being adapted to interlock with the arms of the second section, such arms being of a length substantially equal to the Width of the bases of the rails, and a removable l J 5 MATTER-N.
